Extreme Weather and Drought Are Here to Stay

Extreme Weather and Drought Are Here to Stay | GIS in Education | Scoop.it
From www.nytimes.com - August 21, 2012 11:43 PM
It is increasingly clear that we already live in the era of human-induced climate change, with unprecedented weather and climate extremes.

 

I don't delight in sharing the bad news.  So is this drought just a freak anomaly or a sign of a new normal?

The graphic was not connected to the article. It was linked on a PBS facebook page and I linked the juxtaposition of the graphic and the NY Times article. Here is the FB page: https://www.facebook.com/EarthTheOperatorsManual.Page Personally, an entire century as a baseline of comparison does not feel like cherrypicking data. True the Earth is an incredibly complex system that controlling for all variables is in essence impossible, but denying that the system has changed seems foolish to me. Why has the system changed? I'm okay with that being a reasonable debate worthy of academics.

NASA Earth Observatory - Vegetation Index

From www.youtube.com - May 11, 2012 10:55 AM

The NDVI (Normalized Digital Vegetation Index) is on of the primary methods for detecting healthy vegetation using satellite imagery.  This also serves as a useful way to distinguish between distinct ecological and agricultural regions and the temporal patterns of planting seasons.
